Abstract
Abstract A device for remote viewing of objects in ionizing radiation fields, wherein a fibre-optics channel for transmitting the image of an object under observation beyond the biological shield against ionizing radiation comprises an entrance lens in whose immediate vicinity there is placed one of the ends of a bundle of optic fibres, the other end of the bundle being beyond the biological shield. The fibre-optics channel also comprises a source of heat to maintain at least only the fibre bundle at a temperature ensuring thermostabilization of its light conducting properties in the presence of the ionizing radiation.
